CONTROL UNIT

摘要

The invention relates to a control unit for technical arrangements, devices and/or machines with a microprocessor, comprising a programmable memory and a housing which surrounds the microprocessor and the programmable memory. Data lines extend from the housing for connection to an external device in order for data to be written into the programmable memory. Said control unit is disposed within the housing in such a manner that when the housing is opened, the operability of the control unit is at least partially impaired. The control unit also comprises a control device which checks write access when data is written into the programmable memory by means of the data lines in terms of authorisation. If the write access authorisation thus monitored is correct, then data can be written into the programmable memory.
